Re: Ulf, what of these new AVRs? :)

Higher code sized AVRs are also under price pressure from the many

I was looking at this very issue the other week for a project that is
currently in a mega128 at 8MHz. I need more CPU horsepower, and more
RAM would be very helpful; I was going to just zip up to 16MHz but
looked around for other options. I'm currently paying this:

ATMEGA128-16AI 128K flash/4K RAM/4K EEPROM/48 IO/10ADC/16MHz
$15.05 qty 1
$8.75 qty 100

I can buy:
AT91SAM7S256-AU-001 256K flash/64K RAM/32 IO/55MHz
$12.04 qty 1
$7.28 qty 100

or
LPC2129FBD64-S 256K flash/16K RAM/46 IO/10ADC/60MHz
$10.68 qty 1
$8.52 qty 100

The cost difference at the qty 100 price is almost all eaten by the
need to buy external EEPROM or ADCs, plus the different code density
means I don't get 2x advantage out of the 256K flash.

Are you using that much FLASH for data or code?
If it's for data (const tables, strings and so on...), maybe you could use something like an LPC2103 + M25P40 or something similar...
